Document Type and Number:
WIPO Patent Application WO2002032976
Kind Code:
A3
Abstract:
The invention provides a photo-curable composition for manufacturing thick layers of homogeneous grey to black colour with excellent physical properties as required for use in high tech applications such as for example powder coatings. Such compositions were highly desirable but yet unachieved in the art. The instant composition comprises a radiation curable material as well as both an iron oxide and a phthalocyanine pigment. It has a lightness (L*) of from 0 to 90 and a chroma (C*) of from 0 to 30. The process of hardening said composition by irradiation with light of the wavelength from 150 to 600 nm is also claimed.
